    Hi all, I wanted to share the results of one user of my maps. He was basically running my E50 base map with some small tweaks. Yes, it's overly aggressive for the street. Yes, it hits 21psi for a few RPM. I don't want tuning arguments.... Most importantly, I wanted to show that some schmuck on the Internet could build a decent map that hits insane dyno numbers. I'm not a pro tuner and I don't have time to custom tune everyone's car but I hope folks take my maps and run with them in the interest of the community. http://datazap.me/u/antoniogaj/log-1438459311?log=0&data=4-20 Do your research, log often, ask questions and POST YOUR RESULTS ON THE FORUMS, we are still learning a lot about this car and I think it's best that we document the wins and losses along the way.

    I'd define that more as transient response, or boost threshold. But tomato tomawto. A ST kit w/ a smaller EFR (7163 or 7670) on this car with my VANOS tweaks would probably match the spool / response of the stockers, and crush them in top end. Who wants to build one? hah.

    Quick spool means quicker response and more immediate power for a certain limited time period. Its different from looking at the dyno curve at the same RPM since the dyno curve is based on full throttle from the very low down, so the spool has taken place already and the power for bigger turbos is reading higher, as it should since the lack of spool is not a factor given the full throttle has taken place for quite some time already.

    I'm flashing using the "custom tune" option, shouldn't matter though

    I tried this first, I have concluded that either the driver torque table or the throttle closure table is causing this behavior.

    This! Spool does not necessarily = power. You can definitely have slower spool, but the same or more torque / hp, since you are moving more air volume :)

    Totally sick for sure. Fast as hell and will take 2 people pretty much anywhere. Its just feel like the way I would use it I would hardly ever take advantage of the second seat and would rather have a smaller lighter sport quad or even dirtbike that are both fast as hell too and can go anywhere.

    Exactly. then dont upgrade saying you want to make 550+ but want spool like stock Even if turbos spool slower than stock does not mean they will make less power than stock at a given RPM.

    Our motors put out plenty of power under the curve to get an immediate response to do anything the driver needs to do in a normal driving scenario. Much more than a standard 4 cylinder. Reason why they use small turbos is when BMW like all other manufactures say we are going to produce a economical 300/300 I6 its going to require X amount of boost with X amount of headroom. They properly fit turbo size to designed engine output. When you modify a car your looking to make more power especially if you go upgraded turbo route. If your looking to do that your most likely involved in some type of racing or enjoy the occasional open road at which point your not caring about idle to 3000 RPM. If you race and you find your self needing max power or even any type of power below 3000RPM you should probably get off the track. Not a single type of racing this car can do would need that. Not even autoX. I wouldn't know anything about low end power on these cars though, i've only owned 2 ST N54's with 64MM turbos.

    People , or at least most people want responvive engines due to predictability. That is why NA engines are so fun to drive.. touch pedal -> reaction. When really tracking a car (not the dragstrip) and getting a big heap of power all of a sudden mid corner is less then desirable. In the search for big power sacrifices have to be made. For some that is cool, and they like the kick in the butt from big singles spooling at 4k... For me i like the car responsive. Having 400 whp and fat torque down low on a daily commuter is a big plus. In Belgium here we got some crazy taxes on NA cars with displacement above 3l. Otherwise a NA v8 would have been my choice.

    Just curious, are you flashing where it says jb4 back end or just flashing normally. I'm wondering if that matters?

    Thanks, that much I do understand. But I guess I'm wondering why would BMW choose to make this pipe of metal instead of plastic or radiator hose? It would certainly be a lot cheaper for them. Whilst silicon is sturdy, it is and will be subject to some flex under high pressure, which can affect throttle response.

    I'd return all of the pedal input to throttle values in the flash to stock first and then retest to see if the JB is to blame. These 2 in particular: Torque Request (High) % Torque Request (Low) % 119122

    Hey All, Maybe i'll get a better response here. I have a 2008 BMW 535XI with 126K miles. All stock except BMS DCI's. Now the fun stuff. At 105K the injectors went out. Replaced all injectors, coil packs and spark plugs. 2000 Euro(i'm stationed in germany) When the injectors went out it sent a lot of fuel through the exhaust and i knew i needed new O2's, so i replaced them. The Bank 1 sensor 3 times sue to not loosing the code and the bank 2 once. now at 126K i get the generic P code of P112C and the BMW codes 2C2D, Lambda probe in front of catalytic converter, thrust control 2C3D, Lambda probe in front of catalytic converter, Leitungsfailure 2C39, Lambda probe in front of catalytic converter, dynamics I'm super lost. the car runs fine. Only every now and then does she stumble on herself. I'm thinking of just replacing the bank 2 sensor 1 O2 sensor, but dont want to shell out the $150 if it is not worth it. Has anyone delt with this? Can anyone point me in another direction? Possible wiring issue?

    JoeBezy replied to a thread Oxygen Sensor Voltage in N54
    I know which is which. I was more wondering what voltage should be. I went and replaced the O2 Sensor for the 3rd time and now i get the generic P code of P112C and the BMW codes 2C2D, Lambda probe in front of catalytic converter, thrust control 2C3D, Lambda probe in front of catalytic converter, Leitungsfailure 2C39, Lambda probe in front of catalytic converter, dynamics I'm super lost. the car runs fine.

    As you can see from the last picture, these are wire reenforced hoses, like for instance radiator hoses. With the turbo pressures involved you can not expand these sturdy hoses all that much, if any. They are not like balloons.

    What you need to understand is i don't have a welder to pay or different employees to pay to create this kit. I am the welder/fabricator; No middle man. Now please can we get back on topic to my thread i created for my sales. Too much VM advertisement going on in this thread. Thank you
